v INVALID BED.

Application filed April 21, 1926. Serial 110.1085. I

This invention relates toaninvalid'bed,

- A further object is to provide a supple- I mental structure of this type 'which,under normal conditions, is positloned with the V belts resting upon a mattress of the usual type mounted on'the bed, simple and efficient means beingemployed..whereby the supplemental frame or hammock can be raised or lowered readily relative to the mattress. I y

the supplemental frame a back lift which is yieldingly supported and by the use of which the patient can be supported comfortably in a sitting or reclining posture.

Another object is to provide an invalid bed which, when not in use can be folded or collapsed so'as to occupy the minimum space, the construction of the bed being such that any of the working ,parts thereof can be easily operated by a person of average strength, the diflerent adjustments being effected quickly and the entire.- structure' being sufficiently durable to withstand any of the strains to which the device might be subjected under the severest tests while in use.

. Another object is to provide means where by the Various necessaryappurtenances may be properly combined with and adjusted relative to the bed.

With the foregoing and other objects in view which will appear as the description 40 proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the preciseembodiment of'the invention herein disclosed may be made withinthe scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

Theseend legs are connected by crossed braces 5 secured-to the'legs and serving to hold the legs at each end against movement relative to eachother. Additional braces 6 connect the corner posts or legs 1 to the siderails- 3. These braces are de tachablyconnected either to the legs or to the. side rails and, whe unfastened, will allow the frames formed .by the legs and V braces 5 to fold relative to the side rails 3.

desiredmeans can be. utilized for de-v tachably securing-these braces 6 at one or both ends.

rForked brackets 7 are mounted .on the upperends of the corner posts or legs 1 and the brackets on the posts orlegs at the foot of the bed are providedwith pulleys 8 while similar pulleys 9 are mountedinthe brackets 7 at the upper ends of the other posts or legs lr Pulleys '10 are journaled inthe legs 1 below pulleys 8 and side rails 3 and additional pulleys 1 1 are journaledin the remaining posts lbelow the pulleys 9 and the side rails 3. Brackets 12. areconnected to the end frame members 4 at the centers thereof and journaled in these brackets is a longitudinal shaft 13 to one end portion;

of which is secured a ratchet wheel 14 adapted to be engaged by a pawl 15 whereby rota-4 tion of the shaft 13 in one direction can be prevented. Shaft 13 may be provided with a forked end 16 in which a crank arm 17 ispivotally mounted. By'means of this crank arm v the shaft 13 can be rotated one direction.

Any suitable arrangement of'slats S can be provided in the bed frame, theseslats being supported preferably by the flanges 3 asshown'in Figure 4. These slats are designed to support av mattressM of the usual or any preferred construction.

mental or hammock frame 18 is designed to rest upon the mattress Mand is preferably formed of a metal tube or pipe bent to form the sides. 19 and 20 of the supplemental frame and one end21. The other end of'the frame is formed of a separate length of pipe indicated at 22 coupled to the side 19 by an elbow 23 and tothe side 20 by a coupling orunion 24. Claim 18 is preferably longer than the frame of the bed so that thejend portions thereof will project between the corner posts or legs 1 as shown particularly in Figures 1 and 2. Mounted on the side19 of the supplemental frame 18 are sleeves 25 each of which is provided, at one end, with a toothed collar or ratchet 26 integral therewith. The sleeves 25 are held spaced apart by collars 27 mounted jonthe side 19 of the frame 18 and fastened in positionby set' ception of retaining screws 33 or the like engaging the sleeves. The sleeves 25 can be .of any length desired and any desired number of the sleeves can be used.

Secured to the side 20 ofthe supplemental frame are gripping strips 34 similar to and mounted in the same manner as the strips 31,

. these strips 31and 34 being directly opposite each other, each strip 31 being of the same length as the corresponding strip 34 on the opposite side of the supplemental frame. Belts 351are designed to be used in connection with the strips 31 and .34. One end of each belt 35 isinserted betweenone strip 34 and the side 20' and is then lapped about said side 20 so as to clamp upon that end portion "of the belt in engagement with strips34. Said belt is then carried over the Opposed A supple sleeve 25 and is then inserted. between. said sleeve and the strip 31. By means of a span-. ner wrench or other suitable tool sleeve 25 is rotated so that the teeth of ratchet 26 will slip past the pawl 30. In this way the belt will be wrapped about sleeve 25 and the said belt can be made taut. Obviously any weight applied to that portion of the belt stretched across the frame will tend to bind theends of the belt with increasing pressure against the side 20 or the sleeve- 25 sothat the belt will not become detached. However by loosening thc bclt so that there is no pressure upon it the ends can bewithdrawn readily from positions back of the strips 31 and said belts can therefore be readily removed and other belts substituted therefor. Thus the beltscanbe easily cleanedby completely detaching them from the supplemental frame, being possible to substitute clean belts for them. In using a spanner wrench Extending from the sides of thesupplemental frame between two of the belts are upstanding brackets .36 to whiclrare pivfor the purpose of rotating each sleeve 25, "the same is preferably placed in engagement with the ratchet teeth 26. a

otally connected heads 37 each of which has 7 an arcuate flange38 along "the bottom thereof. An arcuate series ofapertures 39 is provided in each head and any one of these apertures is adapted to receive a pin 40 extending inwardly from the bracket36, thus to hold the head against rotation about its pivot 41. oneend to the forward portion of each of the arcuate flanges 38 and is attached at its other end to a spring 43. This s ring is adjustably connected by a turnbuck e 44. or the like to the end portion 21 of the supplemental frame. This spring43 obviously exerts a continuous pull through the steel cable 42 upon the arcuate portion .38 of the head A steel cable 42 is secured at 37. Consequently when a pin 40 is removed from each head 37, the said disks or heads 37 w ll be rotated by thesprings; These disks orheads37 are provided with sockets 45 in which are seated the lower ends of the sides ofa frame 46 forming a part of a back rest.

The sides of this frame are connected by an endless belt 47 which fits transversely around the frame. This belt can be easily slipped onor off of the frame as will be apparent by referring to Figure 2. Ob-

viously when the pins 4Q are removed the frame Wlll swing upwardly under the action of the springs 43 so as to afford a comfort able back rest which will adjust itself autohas been brought to a desired position the pins 40 can be inserted so as to prevent fur ther movement. When not in use the back matically to the patient After the back rest l rest can be swung downwardly between the I sides of the supplemental frame and there held by insertingthe pins 40 in the proper 48 arranged in pairs. 'lhese ropes are extended upwardly from the frame over the pulleys 8 and 9 and thence downwardly under the pulleys 10 and 11 respectively and inwardly to the shafts 13, the sald ropes being securely attached to this shaft. Thus when the shaft 13 is rotated in one direction all of the ropes will be wound thereon and they will pull upwardly on frame 21 so as to elevate it relative to the mattress M. The supplemental frame can be held at anydesired elevation by means of the pawl 15 1n engagement with the ratchet 14.

Under normal conditions the supplemental frame is in its lowermost position with the belts resting on the mattress. If the back rest is not to be used it can be removed bodily by disconnecting the heads or disks 37 from the'brackets 36. When it is desired to raise the patient from the mattress the belts 35 are drawn taut and the supplemental frame 18 is elevated as heretofore explained. Any one of the belts can be adjusted while the patient is thus supported so as to provide the greatest comfort.

The patient while thus supported can be bathed readily and can be given any necessary attention. By loosening one belt at a time the samecan be removed and another substituted therefor.

The particular construct-ion of the bed lends itself readily to the attachment of .with a bore extending .therethrough from top to bottom as at for the reception of a standard 51. This standard may be provided at its upper end with a laterally extending arm 52. Ears 53 engage this arm and extend downwardly from a tray 54. A collar 55 on the arm constitutes an abutment for one of the ears. A threaded stem 56 engages and extends from the free end of the arm 52 and has a spring 57 thereon confined between one of the ears 53 and a head 58-011 the stem. Thus the spring serves to thrust one ear 53 tightly against the collar 55 so as to holdthe tray at a desired angle. By sliding the tray against the action of the spring 57, however, the same can be adjusted angularly so as to be supported in any desired position over the bed. By means of a set screw 59 the standard 51 can be secured firmly within the bore 50.

One or more sleeves 60 can be mounted to slide and rotate on the section 22 of the supplemental frame. Each of these sleeves can be held against movement by a set screw 61 and is formed with an extension 62 through which a bore is extended. This bore can receive a shank 63 extending'from a foot rest 64 or it can receive a shank 65 i of an extensor pulley 66. By providing two of these sleeves 60 both foot rest and the extensor pulley can be connected to the bed at the same time. Set screws 67 can ofcourse be used wherever it is desired to hold any of the parts against movement relative to the sleeves 60. Obviously any other desired attachment can be used in lieu of or in addition to those already described. What is claimed is:

'The combination with a tubular frame, of

a plurality of alining sleeves mounted for rotation on one side of the frame, collars;

mounted on said side of the frame bet-ween the-ends of the sleeves, means for fastening the collars tovsaid side of the frame to hold them against rotation and to hold the sleeves against longitudinal movement, a pawl pivotally mounted on each collar, a ratchet collar rotatable'with each sleeve and normal- 1y engaged by the adjacent pawl, thereby to hold the sleeve against rotation in one direction, a retainingstrip extending longitudinally of each sleeve, a belt having one end portion insertible between one of the sleeves and the retaining strip thereon, means for tightening said strip upon the inserted end of the belt, said end of the belt being foldable back over the retaining strip thereby to be compressed between the wraps of the belt when wound on the sleeve, a-nd'means for attaching each belt to the opposite side of the frame, each of the sleeves being rotatable independently of the other sleeve, thereby to effect independent adjustment of the belts by winding and unwinding them from the respective sleeves.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.

CHARLES E. PATTERSON.
